CCSD Code C2610: Excision/Biopsy of Lacrimal Sac Billing Guide

Key Takeaways

CCSD Code C2610 describes the Excision or Biopsy of the Lacrimal Sac, a distinct oculoplastic procedure billed in UK private healthcare.

Excision and biopsy are clinically different: excision removes the sac entirely, while biopsy samples tissue for histology. Use the correct code for the procedure actually performed.

Pre-authorisation from insurers such as Bupa, AXA Health, and Allianz Care is typically required before submitting a C2610 claim. Missing it is the leading cause of denial.

Pabau’s claims management software supports CCSD code submission, audit trail documentation, and electronic billing via Healthcode for UK private practices.

Wrong code, delayed payment. That is the billing reality for oculoplastic surgeons and ophthalmologists who use one lacrimal code when the procedure warrants another. CCSD Code C2610 covers a specific and relatively uncommon procedure. Misapplying it, or confusing it with adjacent lacrimal codes such as C2540 or C2640, leads to claim rejections that cost UK private practices significant administrative time to resolve.

This guide covers everything UK private healthcare providers need to bill CCSD Code C2610 accurately: the procedure definition, clinical indications, documentation requirements, insurer-specific guidance, and the submission workflow from theatre note to settled claim.

CCSD Code C2610: Excision and Biopsy of the Lacrimal Sac

CCSD Code C2610 is listed in the CCSD (Coding, Classification and Schedule Development) Schedule as Excision/Biopsy of Lacrimal Sac. It sits within the ophthalmology chapter of the procedural schedule and applies specifically to surgical intervention at the lacrimal sac itself, not the nasolacrimal duct or canaliculi.

One important disambiguation: the US HCPCS system contains a code also labelled C2610, but that code has been deleted and has no clinical relationship to the UK CCSD procedure code. Any online lookup using US coding databases will return irrelevant results. Always verify against the official CCSD schedule, which requires a registered login to access.

CCSD Code C2610 Clinical Indications

The lacrimal sac sits at the medial canthus, collecting tears from the canaliculi before they drain into the nasolacrimal duct. Pathological changes to this structure typically present as epiphora (chronic tearing), recurrent dacryocystitis (lacrimal sac infection), or a medial canthal mass. When imaging or clinical examination raises concern for a neoplastic or cystic lesion within the sac, biopsy or excision becomes the appropriate intervention.

Common clinical scenarios warranting CCSD Code C2610 include:

• Suspected benign or malignant lacrimal sac tumour (papilloma, mucoepidermoid carcinoma, lymphoma)
• Persistent dacryocystitis unresponsive to conservative management with an atypical sac appearance on imaging
• A palpable medial canthal mass requiring tissue diagnosis before definitive treatment planning
• Removal of a previously diagnosed benign lacrimal sac lesion following surveillance

C2610 does not cover dacryocystorhinostomy (DCR), which is coded separately under C2540 (external DCR) or C2542 (endoscopic/laser-assisted DCR). Surgeons performing a DCR with incidental sac biopsy should refer to current CCSD bundling rules before appending both codes to a single episode. According to the CCSD Technical Guide (October 2025), ancillary procedures carried out as part of a primary operation may be subject to bundling restrictions.

CCSD Code C2610: Excision vs Biopsy

The forward-slash notation in C2610 signals that the code covers two procedurally distinct operations under a single code descriptor. This is common in the CCSD schedule for procedures sharing anatomy and surgical approach. The clinical distinction matters for operative documentation even when both map to the same billing code.

Excision refers to complete removal of the lacrimal sac and is typically performed when a neoplasm has been confirmed or when chronic disease has rendered the sac non-functional. Biopsy involves removing a tissue specimen for histological analysis while leaving the sac in situ or partially intact. The surgical note must state clearly which procedure was performed, because insurers may query the operative approach during a claim review.

The table below summarises the key billing attributes of CCSD Code C2610 for quick reference.

CCSD Code C2610 Documentation Requirements

Incomplete documentation is the primary reason CCSD Code C2610 claims are queried or rejected. Insurers need specific evidence that the procedure performed matches the code submitted, and that the clinical decision to proceed was appropriately justified.

CCSD Code C2610 Operative Note Requirements

The operative note must contain the following elements for a C2610 claim to withstand audit:

• Procedure type clearly stated: “Excision of lacrimal sac” or “Biopsy of lacrimal sac” (not a generic reference to “lacrimal surgery”)
• Clinical indication documented: the presenting diagnosis, imaging findings, or prior biopsy result that justified the intervention
• Laterality: left, right, or bilateral (where applicable)
• Anaesthetic type: general anaesthetic, monitored anaesthesia care, or local with sedation, as anaesthetic costs are typically billed separately
• Histology referral: for biopsy procedures, confirmation that tissue was sent for pathological analysis and the laboratory reference
• Surgeon’s name and GMC number
• Date and site of procedure

UK private healthcare providers registered with the Care Quality Commission (CQC) must also retain operative documentation in the patient record for a minimum period in accordance with clinical governance standards. The Private Healthcare Information Network (PHIN) mandates outcome reporting for surgical procedures across all recognised private providers, which adds a secondary data trail alongside the billing record.

Avoiding CCSD Code C2610 Claim Denials

Beyond the operative note, several documentation errors generate denials specific to this code. Referral correspondence is one of the most commonly overlooked requirements. The insurer will typically check that the procedure was performed by a consultant within their recognition network and that a valid referral from a Bupa-recognised or AXA-recognised GP preceded the episode.

Three other denial triggers appear regularly in ophthalmology claims:

• Pre-authorisation not obtained: Most insurers will not pay retrospectively if authorisation was not sought before the procedure. Check each insurer’s rules via their provider portal before operating.
• Unbundling errors: Submitting C2610 alongside C2540 (DCR) without supporting CCSD unbundling approval may trigger an automatic edit. The CCSD Technical Guide defines when supplementary codes are permissible alongside a primary procedure code.
• Incorrect code for procedure performed: Using C2610 when C2640 (Incision of Lacrimal Sac) was the actual procedure performed will result in a mismatch between the operative note and the claim. Incision and excision are distinct interventions.

Insurer Fee Schedules for CCSD Code C2610

UK private insurers publish fee schedules that list maximum reimbursable amounts for CCSD-coded procedures. These schedules are updated periodically; figures stated here are indicative and should be verified against each insurer’s current published schedule before invoicing.

The Guernsey Government’s published Surgical Private Fees document (2021) listed C2610 at £1,040.00. Mainland UK insurer reimbursement rates for equivalent CCSD ophthalmology codes vary considerably by provider panel tier, hospital facility, and consultant recognition status. The table below shows the insurer portals where current C2610 fee information can be verified.

Each insurer uses the CCSD schedule as its procedural coding foundation, but the fee attached to C2610 may differ between plans. Consultants working across multiple insurer panels should check applicable rates at the time of booking, not at the time of invoicing.

How to Submit CCSD Code C2610 Claims

Claim submission for CCSD Code C2610 follows the standard UK private healthcare billing workflow, but the low procedure volume for this code means that billing errors often go undetected until a claim is queried months later. Getting the submission right the first time avoids write-offs.

Step-by-Step Billing Workflow for C2610

1. Confirm insurer recognition and referral: Verify that the operating surgeon is recognised by the patient’s insurer and that a valid referral (from a recognised GP or specialist) is in place before proceeding to theatre.
2. Obtain pre-authorisation: Contact the insurer before the operation date. Provide the CCSD Code C2610 descriptor, the relevant diagnostic context (e.g. suspected lacrimal sac tumour), and the planned hospital or clinic facility. Retain the authorisation reference number.
3. Complete the operative note immediately post-surgery: Include all elements listed in the documentation requirements section above. Delayed note completion is a common audit vulnerability.
4. Raise the invoice using CCSD Code C2610: Apply the correct consultant fee in line with the insurer’s current fee schedule. Anaesthetic and facility fees are typically submitted on separate invoices by the anaesthetist and hospital, not by the surgeon’s practice.
5. Submit electronically via Healthcode: Most UK private insurers accept HBIS XML-formatted claims submitted through Healthcode. Paper submission is permitted by some insurers but delays processing. Attach the pre-authorisation reference and confirm the procedure date matches the operative note.
6. Track claim status: Monitor the claim through your billing system or Healthcode portal. Query any outstanding claims at 30 days. Flag remittance advices that query the C2610 code for prompt response.

Practices using Pabau’s claims management software can link the CCSD code directly to the patient’s treatment record, generate Healthcode-compatible invoices, and track claim status without switching between multiple systems. This is particularly useful for low-volume surgical codes like C2610, where manual tracking is most likely to introduce errors.

Related CCSD Lacrimal Codes: Avoiding Bundling Errors

The CCSD schedule includes a family of lacrimal drainage codes. Selecting the wrong code for the procedure performed is one of the most avoidable billing errors in ophthalmology practice. Each code covers a distinct intervention, and the clinical distinction maps directly to the surgical approach documented in the operative note.

Bundling rules require careful attention when a surgeon performs CCSD Code C2610 alongside another procedure in the same episode. The standard CCSD rule is that a secondary procedure attracts a reduced fee (typically 50% of the listed rate for the lower-value code), but some insurer contracts modify this. Always review the applicable insurer’s fee schedule and the CCSD Technical Guide before appending secondary codes to a C2610 claim.

Practices can reduce bundling error risk by using digital clinical documentation tools that link the procedure code to the operative note at the point of record creation, making code-to-note mismatches visible before the invoice is raised.

Billing CCSD Code C2610 in a Private Ophthalmology Practice

Excision and biopsy of the lacrimal sac is a low-frequency procedure in most private ophthalmology practices. That low volume creates specific billing vulnerabilities: staff are less familiar with the code, insurer pre-authorisation pathways receive less practised, and claim errors may go unnoticed for longer. Practices operating within oculoplastic surgery or general ophthalmology service lines should assign a named billing coordinator responsibility for surgical code claims.

From a workflow perspective, the key difference between CCSD Code C2610 and more routinely billed ophthalmology codes (such as cataract extraction or intravitreal injection codes) is the almost-certain requirement for a pre-operative insurer consultation. The clinical presentation (medial canthal mass, suspected lacrimal sac tumour) may require imaging reports and biopsy results to support the pre-authorisation request. Assembling this documentation in advance reduces delays and avoids the situation where a date is set before authorisation is confirmed.

Histology fees: When CCSD Code C2610 involves a biopsy, the specimen is sent to a pathology laboratory. The histology fee is typically invoiced by the laboratory separately from the surgeon’s fee and is not included within the C2610 reimbursement. Confirm with the insurer whether the laboratory is within their recognised network before sending the specimen.

Medical practices using lab management software integrated with their practice management system can track specimen referrals and histology results within the same patient record, reducing the risk of a missed result or an unreported histology charge.

Conclusion

CCSD Code C2610 is a precise, low-volume billing code that rewards careful preparation. The most expensive errors, denied claims and insurer audits, almost always trace back to one of three points: missing pre-authorisation, an operative note that does not match the submitted code, or a bundling error with an adjacent lacrimal code.

Pabau’s claims management software is built for exactly this kind of workflow: linking CCSD codes to clinical records, generating Healthcode-compatible invoices, and providing the audit trail that insurers expect when they query an oculoplastic claim.
